在单试样三曲线关联分析的基础上,提出一种新的单试样测定断裂韧度阻力曲线的分析方法和步骤,编制了计算机应用程序。该方法反映裂纹试样的宏观断裂过程,与标准多试样法的测定结果相符。
Based on the single-sample three-curve correlation analysis, a new single-sample analysis method and procedure for measuring the fracture toughness resistance curve are proposed and the computer application program is compiled. The method reflects the macroscopic rupture process of the cracked specimen, which is consistent with the standard multi-specimen method.
